Why can't I update Photogize Lab?

This is usually caused by corrupted Photogize Lab installation files that Windows maintains on your PC.

To fix this problem, remove the uninstallation key entry for Photogize Lab from the registry:

PLEASE NOTE: You should only do this if you have a thorough understanding of the Windows registry. For more information on backing up and restoring the Windows registry, please see this Microsoft KB article:

The key entry is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{F4142AAD-BFC4-44B6-BF61-07AAC984CF00}

Run Regedit

Double Click on "HKEY_LOCAL_MACHINE"

Double Click on "SOFTWARE"

Double Click on "Microsoft"

Double Click on "Windows"

Double Click on "CurrentVersion"

Double Click on "Uninstall"

Right Click on "{F4142AAD-BFC4-44B6-BF61-07AAC984CF00}"

Select "Delete" from the menu.

After this key is deleted, you can run the Photogize Lab installer. The installer will treat the installation like a new installation, but all existing Photogize Lab settings will be maintained.
